IMPROVEMENT IN BASKET ATTAGHMENTSPOR PISI'ONS OP DEEP WELL PUMPS.

@In Stimuli nimh tu in'tes Entert atent mit mating part nf its samt TO ALL WHOM IT MAY CONCERN:

Bc it known that I, ERASMUS D. BROWN', of thclcity of Buialo, county of Erie, and State of New York, have inventeda new Basket Attachmentfor Pump Pistons; and I do hereby declare thatA the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this speciiication, in which- Figure I is an elevation of my improvement, as connected with a pump piston and sucker-rod for practical use; and

Figure II is a top plan.

The nature of this invention relates to the attachment of a slotted flaring metallic basket to the upper end of a pump piston in such manner that the basket will catch and hold` any broken or loose rivet or other thing which may happen to fall into the pump barrel, and thereby prevent any wedging or clogging of the pistou or pump barrel. Y y

Having reference to the drawings, A represents an ordinary pump piston,and B'represents a slotted and aring metallic basket, which is placed on the top of the piston with the Haring end uppermost. The flaring' and open end just lls the bore of the pump barrel, (working freely and easily thereim) so that if any rivet which connects the woodand iron parts of the sucker-rod should break, work loose, and fall down, which is often the case, this basket will catch and hold it, and' thereby prevent it fromV clogging or obstructing the working of the piston. Y l

It often happens in pumping oil wells that the rivets which are used for connecting they wood and iron parts of the 'sucker-rods together break or work loose and fall down into the pump barrel, and thereby clog and prevent the piston from operating. It r*often happens, too, that chips, splinters from the sucker-rods, ando other obstructionsfall down into the 4pump barrel and clog and choke it up. My improvement is intended to remedy these diiculties. The slots b inthe basket are of sudicient area to allow all .the liquid which the piston can raise to pass through freely, so that the basket is not the slightest obstruction to the free operation of the piston. The iron end of the sucker-rod is shown at C. This is` connected to the pump piston by means of a screw thimble within the basket, represented by the dotted lines D in Fig. I, and by the circle D in Fig. II. The

thimble screws on to the top of the piston, and the sucker-rod screws into the thimble. The basket may sit loosely on the top of the piston, and'may be connected with any form of pistou.

What I claim as my invention, and 4desire to secure by Letters Patent, is-l- The slotted daring basket A, for the purposes and substantially as described.
